SASH FASTENER.

Application filed January 8, 1.924. 'Serial No. 685,002.

This invention relates to a sash fastener, It has for its object a fastener, that is supported on the lowcr sash of a window and is adapted to clamp the upper sash thereof. The essential element of the fastener is an Iadjustable screw, which is located with its longitudinal axis inclined to a horizontal plane, and which carries a clamping block adapted to bear against the upper sash of the window. The inclined position of the screw causes the clamping block to bear with increasing pressure, if it is attempted to lower the upper sash, when said clamping block bears thereon. To lower the upper sash the .screw is turned, to cause the block to be removed out of the path of said upper sash.

In the accompanying drawings Fig. 1 shows a front view of the sash fastener in position with a pair of sashes of a window; Fig. 2 represents a section of Fig. 1 on the line 2, 2 and Fig. 3 indicates a top plan view of Fig. 2.

In the drawings the window is shown with an upper sash having the bottom rail 20 and the vertical members 21; and a lower sash with the top rail 25 and the Vertical members 26.

The sash fastener comprises a bracket with the bottom wall 50, which has extending up therefrom the side walls 51 with the round journal openings 52, and the depending aprons 53 and 54. A clamping screw 55 extends through the apron 53 and engages the rail 25, while the apron 54: hugs the outer face of the rail 25.

A bracket is indicated with the U shaped head 60, which extends from the curved member 61. Journal pins 62 rectangular in crossssection extend from the member 61 and are seated in the journal openings 52. A plate spring 64 extends into the U shaped head and is fastened thereto.

A clamping screw 65 extends through openings in the head 60 and has formed at one end the eye 66, and also has attached to its other end the tapered cup 67. In the latter is fastened the tapered plug 68. A nut is in threaded engagement with the screw 65 and is located in the U shaped head 60.

In the position of the parts indicated in the drawings the outer face of the plug 68 bears against one of the vertical members 21 of the upper sash, and if it is attempted to lower the upper sash, the said plug 68 will bea-r .again-st .said member 21 with increasing pressure. VIf it is desired to lower the sash, the screw 165 is Vturnedy toidisengage .the plug .68 from .the member 21.

The curved member 61 of the U shaped head 60 is disposed to bear against the upper face of the bottom wall 50 of the bracket of the sash fastener, and normally maintains the clamping screw 65 in proper angular position in one direction, while the plate spring 64; normally maintains said screw 65 in proper angular position in the opposite direction. The coaction of the tapered plug 68, when it is attempted to lower the upper sash having the vertical members 2l, results in a cam action between said plug 68 and one of said vertical members 21. The screw 65 must be maintained in the same inclined position, to prevent the plug end thereof swinging up, when it is turned, to bear said plug against one of the vertical members 21, otherwise the plug would ride on the member 21 and not tightly bear against it to clamp the sash in place.

Various other modifications may be made in the invention and the present exemplication is to be taken as illustrative and not limitative thereof,

Having described my invention what I desire to secure by Letters Patent and claim 1s z* 1. In a sash fastener the combination of a bracket adapted to be fastened to a window sash, a second bracket pivoted to the first bracket, a screw supported in the second bracket, a plug carried by said screw adapted to bear against the other sash of the window and, means for the second bracket to normally maintain the latter in operative angular position to produce a cam action between said plug and the second sash with any movement of the sashes to a changed position.

2. In a sash fastener the combination of a bracket adapted to be fastened to the rail of a window sash, a second bracket pivoted to the first bracket and having depending therefrom a. member adapted to bear against the first bracket, to normally locate the second bracket in operative angular position, a screw supported in the second bracket and a plug carried at one end of the screw.

3. In a sash fastener the combination of a bracket adapted to be fastened to the rail of a window sash, a second bracket pivoted to the first bracket and having depending (ill therefrom a inelnber adaptedto bear against engagement; with said nut and a ping Supthe nrst bracket, a screw extending through yported on one end of the screw adapted to 15 the second bracket, a flexible ping for one end of the screw adapted to bear againSt the other sash of the window and aV Spring with one end thereof supported on the screwl and its other end bearing on the irst bracket.

4. In a sash fastener the combination of a bracket adapted to be fastened to the Sash 0i: a window, a second bracket pivoted to the h'rst bracket and having a U ,shaped head, a nut located in the said head, a screw extending through said head and in threaded Vbear against the other sash of the Window, said .second bracket having a member adapted. to bear against the rst bracket to locate said screw in proper operative position.
